I know it goes against conventional wisdom and I know all the pitfalls, but I'm not going to magnetize my jetbikes to their bases.
The only reason I have is that I don't like the way they look. There's just something about that all clear, tiny plastic stand that just "fits" with the feel of the jetbike for me. This looks better to me.
As a side note, I've just got some finishing touches on the last guy for the first 10 man squad.
